Chapter 1755: To Make or Not (Part 2)
Zhao Yanyan knew that Guo Tailai had this batch of gold, but he didn't see it. When I talked about the cost before, it was also because she was used to it during final assembly. No matter what research or design you do, the first problem you face is the problem of funding. The design cost is too high, and the project with too high cost must be given up immediately. There is no way, the country is still poor and military spending is limited, so we can only make some helpless compromises in certain aspects.
But Fatty does these things by himself without considering the cost at all, or in other words, he does not need to consider the cost at all, and it is most practical to consider the technical feasibility first.
No way, seven hundred tons of gold is a huge reassurance, not counting the billions of dollars in Google shares that were just disclosed. In terms of funds, as long as the fat man wants to do it, it is not a problem at all.
Equivalent gold, hundreds of tons of gold, worth billions of dollars, can definitely make the deep submersible that Guo Tailai wants. And based on the size and displacement of Lao Maozi's nuclear-powered deep submersible, as long as three metal ball pressure chambers are strung together, it doesn't even weigh one-eighth of the weight, only 300 tons at most.
Jiaolong has an empty weight of 22 tons, Shenhai 6500 has an empty weight of 26.7 tons, and Alvin is lighter, with an empty weight of only 17 tons. They are all single spherical pressure-resistant cabins, the inner diameter of which is no more than two meters, and there are three people to take in. One can imagine how cramped the space inside is.
Because of the overall low weight and small size, the number of people and equipment that can be accommodated is limited. The underwater endurance of these deep submersibles does not exceed three days. Of course, you may be able to stay a little longer in the "shallow sea" of several kilometers. In the Mariana Trench, let alone three days, just the lonely pressure of that person in the deepest place on earth is enough to make people collapse .
From this point of view, it is admirable that that guy James stayed alone for eight hours alone in the Explorer of the Seas that could collapse at any time. Especially at the deepest point, some accessories have been crushed by the terrible water pressure, and he can still enjoy the scenery of the seabed quietly in it, worthy of the title of "madman".
Guo Tailai will definitely not be "wronged" like him. Since it is going to be built, it must be bigger and more spacious. You can bring more equipment and life support systems, and you can stay underwater for a longer time. To put it simply, you can bring a lot more oxygen. It is even possible to sleep underwater if necessary. There are three spherical pressure chambers with a diameter of three meters, and it is more than enough to sleep two in each.
Zhao Yanyan would be lying if she said she wasn't excited. My fat man insists on doing this stubbornly, not because the space is so comfortable, but because he wants to make technical reserves for the research and development of the same type of equipment in China through this method.
Whether it is casting or forging of large titanium alloy balls, there must be equipment of this level and size. With the help of Fatty's production, these technologies can be researched in advance. Of course, there are also large titanium alloy hemispherical welding, the same is true. As for other buoyancy materials that need to be used, life support systems, batteries and power systems, safety escape systems, and very important underwater acoustic communication systems, they must be studied in advance, and they will definitely be used in the future.
Guo Tailai has done this kind of thing more than once, including the previous "three jumpers in the air" helicopters and super yachts, and now he wants to add a deep submersible.
If his own fat man really made all these things, it might be a bit embarrassing for the domestic research units of the Jiaolong. But this is not a big problem, after all, the other party does not have such a rich and powerful investment regardless of cost, and then again, it is not once or twice that his own fat man embarrasses some domestic research and development institutions, and the embarrassment comes and goes slowly. Also get used to it.
"The dive depth you require is close to twice this. Are you sure that the strength of the pressure chamber can withstand the pressure of the seabed?" No longer entangled in the cost, the senior sister asked a very critical question: "This is related to you. If you fail the test, I will never allow you to ride."
"Thickened titanium alloy spheres should be fine, as long as the thickness exceeds 120 mm, the pressure resistance is not a problem at all." Guo Tailai knew the worry of the senior sister, and replied with a smile: "It's just that the processing requirements are higher. Now we have The large-scale 3D titanium alloy printer, with a diameter of three meters, has been realized, and it can be completely integrated, which is easier than welding two hemispheres. Titanium alloy welding is not easy, and the integrated molding material is more uniform and stronger.”
That's right, Zhao Yanyan also knows that the series of 3D printing projects hosted by the second brother Guo Tailai's dormitory of Zhengyifang Technology, integrated printing is indeed more convenient than separate casting and then welding together.
"If you are still worried that the thickness is too large to be processed, a martensitic high-strength nickel steel that Zhengyifang Technology is developing is about to be completed." Seeing that the senior sister was silent, Guo Tailai immediately continued: "This new type of alloy steel has a higher strength than The TC4 titanium alloy is twice as high, and the compressive strength can be achieved in a thinner case. It’s just that the cost may have to be increased, which is completely acceptable.”
Guo Tailai’s martensitic high-strength nickel steel is the material for the pressure chamber of the Rainbow Fish manned submersible made by Huaxia in the future. The Rainbow Fish is designed entirely for diving into the Mariana Trench, and its structure is stronger. Performance is better.
Zhao Yanyan smiled wryly as she listened, and co-authored with her own fat man, before doing many things, he had already finished researching a batch of advanced technologies. There are new materials for the pressure chamber, such as titanium alloy. The portholes and observation holes are generally made of highly transparent methacrylic resin, but Fat Company has long ago developed transparent metal, which has better performance.
The buoyancy material Jiaolong project team still needs to customize it from the UK in advance, but Zhengyifang Technology has been researching and developing it since the year before last, and it is almost completed, so it is not a problem at all. Battery Guo Tailai has a supercapacitor that has been successfully developed but the cost is still extremely high, but is this a problem for the fat man?
The biggest problem has been solved. The remaining working systems and underwater acoustic communication are being researched in China. Guo Tailai has also invested in it. The power system is also being developed by research institutes. It seems that all that is left is production and assembly. up.
From this point of view, Fatty wants to build an ideal manned submersible with a three-sphere pressure-resistant hull. There are no technical and equipment obstacles. He just needs to determine the design plan, produce, assemble and test, and consider the cost.
"Don't make a decision yet, what should you do when you go back to Gusu." The senior sister also lost her mind: "I will report this situation to my superiors tomorrow and see what the superiors think. However, I guess the superiors will not allow it, even if Even if the three spheres are connected in series, the Russians will also think of that nuclear submarine, and the country will not allow you to take the initiative to put yourself in a dangerous situation."
